Subject: ALSA: oxygen: Xonar DG(X): cleanup and minor changes
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3f49a66f6ceff1c87b49858644771c17763902ab;p=linux-beck.git

ALSA: oxygen: Xonar DG(X): cleanup and minor changes

Remove old SPI control functions, change anti-pop init
sequence, remove some garbage from structures. The 'Apply' functions
must be called at the mixer initialization, otherwise
mixer settings sometimes will not be applied at startup.
